Understanding Our Teeth: Baby Teeth vs. Permanent Teeth

Our teeth play a crucial role in chewing, speaking, and maintaining facial structure. Humans have two sets of teeth in their lifetime:

Baby Teeth (Primary Teeth)

• Also called deciduous or milk teeth.
• 20 in total (10 upper, 10 lower).
• Start appearing around 6 months and are usually all in by age 2-3.
• Begin falling out around age 6, replaced by permanent teeth.

Permanent Teeth (Adult Teeth)

• 32 in total (including wisdom teeth).
• Start coming in around age 6 and continue until early adulthood.
• Include incisors, canines, premolars, molars, and wisdom teeth (which may emerge in late teens or early 20s).

Key Differences

Feature Baby Teeth  Permanent Teeth

Number 20                  32 (including wisdom teeth)

Appearanc Small, white Larger, slightly yellowish

Roots Shorter,    Longer, firmly anchored

Enamel Thinner,    Thicker, but still needs care

Lifespan Temporary Permanent (must last a lifetime)

How to Protect & Maintain Healthy Teeth

1. Proper Brushing & Flossing

• Brush twice daily (morning & before bed) with fluoride toothpaste.
• Use a soft-bristled toothbrush to avoid gum damage.
• Floss daily to remove plaque between teeth.
• For kids, supervise brushing until age 7-8.

2. Healthy Diet for Strong Teeth

• Limit sugary & acidic foods/drinks (soda, candy, citrus).
• Eat calcium-rich foods (milk, cheese, leafy greens).
• Drink water (helps wash away food particles).

3. Regular Dental Checkups

• Visit the dentist every 6 months for cleanings & checkups.
• Sealants (for kids) can protect molars from cavities.
• Fluoride treatments strengthen enamel.

4. Avoid Harmful Habits

• No smoking/vaping (increases gum disease & oral cancer risk).
• Don’t chew ice/hard objects (can crack teeth).
• Limit teeth grinding (bruxism)—use a night guard if needed.

5. Special Care for Baby Teeth

• Even though they fall out, decay in baby teeth can affect permanent teeth.
• Start cleaning gums before teeth appear (use a soft cloth).
• Once teeth emerge, brush gently with a tiny smear of fluoride toothpaste.

Final Advice

• Start good habits early—kids learn from parents!
• Replace toothbrushes every 3-4 months (or when bristles fray).
• If a permanent tooth is knocked out, keep it moist (in milk/saline) and see a dentist immediately.
• Taking care of your teeth ensures a lifetime of healthy smiles!
